In recent years, the usefulness of High Frequency Percussive Ventilation (HFPV) has been clinically valued as a suitable alternative to conventional mechanical ventilation especially in particularly conditions (for example in pulmonary resection [1]). However, sophisticated and expensive equipments are required for measuring the respiratory parameters ...

COTTON ELONGATION MEASUREMENT USING HIGH VOLUME INSTRUMENTS
Transactions of the ASAE, 1998Fiber elongation is an important physical property of textile fibers. Elongation determinations were initially performed on individual fibers. This is no longer practical. Individual cotton fibers vary considerably in character and the testing of single fibers is very time consuming. Current testing methods use a bundle of fibers.

An earlier study confirmed the influence of cotton fiber length characteristics on the High Volume Instrument™ (HVI) strength measurement and devised a quantitative correction factor to compensate for the effect. The current paper investigated the validity of two important assumptions utilized in the previous study.

A next-generation optical surface form inspection instrument for high-volume production applications
SPIE Proceedings, 2012Despite the introduction of phase-shifting interferometers in the 1980's, high volume catalog and camera production lenses are still inspected using qualitative visual fringe inspection methods. This error-prone inspection technique requires the human operator to quickly judge whether the lens “passes” or “fails” based on the appearance of the ...
